Setting up an IRF fabric (distributed devices)
This chapter guides you through the IRF fabric setup procedure for M9000 security gateways.
Hardware compatibility
An M9000 security gateway can form an IRF fabric with devices from the same series.
General restrictions and configuration guidelines
For a successful IRF setup, follow the restrictions and guidelines in this section and the setup procedure
in " Setup and configuration task list ."
IRF fabric size and member ID restrictions
To ensure a successful IRF setup, follow these IRF size and member ID restrictions:
• An IRF fabric can contain a maximum of two devices.
• The member ID assigned to a member device must be 1 or 2.
Software requirements
All IRF member devices must run the same software image version. Make sure the software auto-update
feature is enabled on all member devices.
MPU requirements for distributed devices
Every IRF member must have a minimum of one MPU.
IRF physical interface requirements
Candidate IRF physical interfaces
Use the following interfaces for IRF links:
• XFP ports.
• QSFP+ ports.
• CFP ports.
QSFP+ port restrictions
You can use QSFP+ (40 Gbps) ports for IRF links, or use 10-GE breakout interfaces of a QSFP+ port for
IRF links. To split a QSFP+ port, use the using tengige command.
When you use the 10-GE breakout interfaces of a QSFP+ port for IRF links, follow these restrictions and
guidelines:
